Reference Data
A.2 Performance specifications
A.2.1 General
Reference conditions
(1)
Single flexible probe mounted in a 4" pipe. Normal indoor temperature (68° - 79 °F, 20° - 26 °C)
water.
Reference accuracy
Repeatability
±0.08 in. (2 mm)
(2)
Ambient temperature effect
Less than 0.01% of measured distance per °C
Power module battery life
9 years at one minute update rate
(3)
A.2.2 Environment
Vibration resistance
No effect when tested per the requirements of IEC60770-1 (1999): High Vibration Level - field or
pipeline (10-60 Hz 0.21 mm displacement peak amplitude / 60-2000 Hz 3g).
Electromagnetic compatibility
 Meets CE 61326:2012 and NE21:2012 if installed in metallic vessels or still pipes.
 Single lead probes are not suited for non-metallic tanks or open atmosphere
applications, due to high susceptibility to strong electromagnetic fields.
(1) Please refer to the IEC 60770-1 (IEC 1292-2) standard for a definition of radar specific performance parameters and if applicable
corresponding test procedure.
(2) According to IEC61298-2 (at reference conditions where averaging at specified measuring points was used to be able to capture specific
parameters e.g. hysteresis, non-repeatability etc.). For field verification where reference conditions cannot be established the repeatability
may be verified if the transmitter is operating in High Performance Mode.
(3) Reference conditions are 70 °F (21 °C), and routing data for three additional network devices.
